BUSSE, OF CHICAGO, ILLINOIS, ASSIGNOR TO CHICAGO RAILWAY EQUIPMENT GOMPAN Y, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS RAILWAY TRUCK CONSTRUCTION Application filed March 5, 1932. Serial No. 597,066.

This invention relates to railway rolling stock and consists in a novel means 7 for guarding, guiding or supporting brake beams.

The main object of the invention is to provide means for supporting a brake beam guard, guide or support member from a plurality of truck elements, at least one of which is subject to relative movement during normal operation of the truck.

Another object is to provide means for partially supporting'a brake beam guard, guide or support member from the truck side frame which will not require the provision of an expensive and fragile elongated arm on theside frame. 7

These objects and others are attained substantially by supporting the guard, guide or support bracket from the truck side frame 7 and from the relatively movable bolster, the

bracket forming a beam between these parts. Means are also disclosed for yieldingly mounting the bracket.

In the accompanying drawings which illustrate the invention 7 Figure 1 is a topview of part of a truck illustrating one form of the invention, portions being section-ed for clearer disclosure.

Figure 2 is an elevation of the same, the truck side frame and the guard, guide or support member being sectioned.

Figure 8 is a vertical longitudinal section taken on the line 3-3 of Figure 2.

Figures 4 to 8, inclusive, 10 to 15, inclusive,

' and 17, 18 and 19 are views corresponding with Figure 2 and showing modified forms of the invention.

Figure 9 is a top view of the form shown in Figure 10, the bolster being shown in section.

Figure 16 is a top view of the form shown in Figure 17. r

In Figures 1, 2, and 3, the bracket 1 mounting the brake beam guard, guide or support Imember 13 has a pair of longitudinally spaced outward projections 2 which are pivoted by means of a pin 3 to spaced lugs 4 extending inwardly from the lower portion 5 of the truck side frame and braced by diagonal ribs 5a. Lugs 4 form a continuasprings 7 which, inturn, support bolster 8.

Bracket 1 has an upwardly disposed inner arm 9 which is secured by means of a pin in the horizontally slotted lugs 10 depending from the under surface of bolster 8. Movement ofbolster 8 relative to the'truck frame will cause pin 11 to slide back and forth in slots 12 which has the effect of decreasing the departure of the guard, guide or support strap 13 from its normalposition. A chair element 14 depending frombrake beam 15 has a rounded under surface 16'which is adapted to adjust itself to various positions of the strap 13, resulting from the movement of bolster 8.

In Figure 4,'bracket 17 is pivoted to disposed bolt23 seated against the bottom of bolster bracket 22 extends, through portion 20, the latter being slidable along the bolt and maintained in engagement with nut 24 by a coiled spring 25. The guard,guide or sup port bracket is normally eyieldingly supported at the bolster end thereof" but in case; of brake hanger failure, .ofl'set portion 20 will engage the lower edge of opening 21 in the bolster bracket.

In Figure 5, br'acket'48 mounting guard, guide or support member 49 has a Z-shaped portion 50 on the outer side extending through an opening 51 in side frame shelf 52. On the'inner side, the bracket has an upwardly offset portion 53 through which extends an upwardly disposed bolt 54. Portion is maintained substantially spaced from the lower fiange'of bolster bracket 55 and'from nut 56by coiled springs 57 and 58 surrounding the bolt. 54. -During normal operation, the bracket 48 will be carried by both shelf 52 and bolster bracket 55 but in case of abnormal depression of the bracket, the lower horizontal end of Z-shaped portion 50 will engage the under surface of shelf 52, causing the bracket 48 to be car- IOI v limiting the mits abnormal downward movement of bolster 59.

7 In Figure 6, guard, guide or support bracket 60 has a Z-shaped outward projection 61 engaging a side frame shelf 62 as in Figure but is provided with a vertical element 63 which is movably mounted in a vertically slotted bolster bracket 64. The operation of this modification is similar to thatof the previous form.

In Figure 7, the guard, guide or support bracket 65 is pivoted to side frame shelf 66 by means of a pin 67. An unbalanced weight 68 pivoted to bolster bracket69 has a comparatively heavy lobe 70 on one side and 'a lighter lobe 71 on the other which bears upwardly against the inwardly pro-- Weight jecting portion 72 of bracket 65. 68 tends to maintain the bracket 65 and stra 73 substantiall in uniform osition P y P 3 28' which is disposed to engage theunderside of shelf 27 after a predetermined inclination of bracket 26, as in Figure '7. The bracket arm '30 is yieldingly supported in bolster bracket .31 by means of a coiled spring 32.

5? The bolt and nut 23 and 24, shown in Figure 4, are eliminated in figure 8w-so that when lip 28 engages shelf 27, the bolster may have continued downward movement without straining the bracket or side frame connection.

In Fi ures 9 and 10, guard, guide or support bracket 33 has a cup-shaped portion 34 beneath pivot 35 and an upward projection 36 on the inner end which extends through 453 11 opening 37 in the bottom of bolster bracket 38, the projection 36 having an enlarged head 39 inside the bolster bracket. Bracket 33 is yieldingly maintained in its normal position by a coil spring 40 seated against cupshaped portion 34 and the under surface of side frame shelf 41. In case of failure of. a brake beam hanger causing the weight of the beam to be supported by, the strap 42, spring 40 will becompressed and the engagement of enlargement 39 with bolster bracket 38 will permit the bolster to cooperate in supporting the strap and beam.

It will be apparent that in this form, the strap 42, when functioning normally as a 1 brake beam guard, guide or support,will be carried by the side frame only and that in case of emergency, when the strap functions as a safety guard, the bracket 33 will be carriedjointly by shelf 41 and bolster bracket In Figure 11, bracket 43 mounting angle shaped guard, guide or support angle 44 has an inner arm 45 extending through an opening 46 in the bolster 47 and resting against the inner edge thereof, and an arm 103 having a hook 104 at the outer end pivoted on pin 105. carried by a bracket 106 depending from the lower surface of side frame 107.

Figures 12 and 19 show inner arms 108 and 109, respectively, on the guard, guide or support bracket extending through and resting on the inner edge of an opening in the under surface of the bolster. Outer arm 110 in Figure 12 has a hook 111 at the end, as in Figure 11, carried on a pin 112 and bracket 113 depending from the bottom of the truck side frame 114, but a bent spring 115' is inserted between the hook and the under surface of the side frame to hold the parts tightly assembled and prevent rattling.

In Figure 19, arm 116 on the guard, guide or support bracket has a Z-shaped portion 117 at the outer end extending through an opening 118 in the bottom of the side frame, the horizontal extreme end 119 preventing the withdrawal of portion 117 when the bracket is in the operating position.

In Figures 13, 14, and 15, the guard, guide or support brackets in each case are pivoted to a bracket on the under surface of the bolster. In Figure 13, bracket 81 has an outward projection which rests upon a short ledge 82 on the truck side frame. 7 In Figure 14, the bracket 83 has an arm 84 extending through an opening'85 in the side frame beneath spring seat 86. In Figure 15, the underframe ledge 87 is provided with a depending loop 88 through which extends the hooked outer end 89 of the guard, guide or sup-port bracket 90.

. In Figures 16 and 17, the guard, guide or support bracket 91 has a pair of U-shaped hook elements 92 on the outerside which engage the inner end of side frame ledge 93, and has an inclined inner arm 94 extending through opening 95 in the bolster bottom web 96. A flat spring 97 is secured to shelf 93, by means of the plate 98'riveted at 99, and extends beneath arm 94 and through opening 95, resting against the inner edge thereof, as. at 101. Arm 94 is normally spaced from the adjacent inclined portion ofspring 97, but under abnormal stress will engage the same, further downward movement of the arm being thereupon resisted di-- rectly by the bolster.

The guard, guide or support bracket shown in Figure 18 has an outward projection pivoted to side frame shelf 76 in the manner illustrated in Figure 2. The lower web 77 of the bolster is provided with an opening 78, and bracket 75 has an angle inner portion projecting through this opening, the angle having a horizontal-top portion 79, normally resting against the inner surface of the bolster bottom web 77, and a vertical portion abutting the vertical lower edge of opening 78. During depression of the bolster, the vertical lower edge of opening 78 will slide downwardly along portion 80 of the bracket, as indicated in broken lines, and the bracket will be maintained substantially in its normal horizontal position.

In this form as well as the forms shown in Figures 1, G, 7, 11,12 and 19, the guard, guide or support bracket is supported from the bolster by means of a lost motion connection, whereby the vertical movement of the bracket is less than that of the bolster.

In each case, the guard, guide or support bracket is carried, at least in emergency, as a beam by both the bolster and the side frame so that the side frame connection may be relatively lightand accordingly less expensive than is the case where a side frame must carry he entire weight of the member under all conditions. Moreover, means is provided for ermitting the movement of the bolster wit out materially affecting any of the functions of the guard, guide or support member and without straining. the bracket or side frame connections.

Obviously, the invention is not limited to the exact details of the embodiments illustrated. In some of the forms, a narrow side frame shelf or ledge is illustrated as forming a continuation of the spring seat, but this element may be applied to other types of trucks than that illustrated and need not be associated with the spring seat. In Figures 11, 12, 14, and 19, the guard, guide or sup-- port bracket is mounted directly on the truckside frame or a depending element, the special shelf or arm being eliminated. These and other variations as will occur to those skilled in the art may be made without departing from the spirit of the invention and the exclusive use of all such modifications as come within the scope of the appended claims is contemplated.
